AI agents call query_project to retrieve information from Workhour without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries project information without side effects. The verb 'query' and the read-only nature of fetching project metadata places it squarely in the Read category. The context of a timesheet/workhour tracking system suggests it retrieves project data for reference purposes.
